Description
제1도는 본 고안을 시공한 상태의 저온탱크 일부단면도.Figure 1 is a partial cross-sectional view of the low temperature tank in the construction of the present invention.
제2도는 본 고안의 요부확대 단면도.2 is an enlarged cross-sectional view of the main part of the present invention.
본 고안은 내·외탱크체로 구축된 다중각(多重殼) 저온탱크에 있어서, 저온액화가스 저장탱크의 하부를 지지하고 있는 페라이트 콘크리트제 기대와 콘크리트제의 탱크 사이에 우레탄포옴을 취부(吹付)하여 발포시켜서 되는 저온탱크의 보냉층에 관한 것으로, 특히 본 고안은 저온 액화가스 저장탱크의 하부를 지지하고 있는 페라이트콘크리트제 기대 외주면과 이 페라이트 콘크리트재 기대가 재치되어 있는 콘크리트제 외탱크 저면이 접속되는 전주면에 미리 전방에 경사면을 형성하고 발포성 우레탄포옴과 같은 보냉재로 형성된 보냉블록을 형성하여 접착시킨 다음, 이의 경사면 상방부터 콘크리트제 탱크의 저면에서 라운드플레이트 및 콘크리트제 외탱크측벽의 라이닝플레이트까지 순차적으로 우레탄포옴을 취부 발포시켜 주어 일련의 보냉층을 형성시켜 줌으로서 콘크리트제 외탱크 내측에 보냉층을 형성하게 되는데, 보냉블록의 전방면이 하향 경사지게 함으로서 이 보냉블록의 전방 경사면과 접하는 우레탄포옴으로 형성된 보냉층의 저면 선단 접속면이 상향으로 경사지게 취부되게 되어 보냉층의 저면 선단 접속면은 보냉브럭의 전방 경사면에 의하여 보냉층의 저면 선단부의 상단부는 점차로 얇은 두께로 경사지게 형성되게하므로서 보냉층 성형시 저면선단부에는 난기포현상이 발생되지 않게함과 동시에 저면선단부가 저온액화가스 저장탱크내에 저온액화가스를 저장하였을 때 또는 저장하지 않았을 때 보냉브럭이 수축 또는 팽창되는 현상에 의하여 발생되는 열응력을 감소시켜주어 보냉층의 저면 선단부가 보냉브럭의 경사면에서 박리되는 현상을 방지할뿐만 아니라 균열되는 현상을 완벽하게 방지시켜 줌으로서 저온액화가스 저장탱크의 보냉기능을 현저히 향상시킬 수 있도록 한 것이다.The present invention is to install a urethane foam between a ferrite concrete base and a concrete tank supporting a lower portion of a low temperature liquefied gas storage tank in a multi-angle low temperature tank constructed of internal and external tanks. In particular, the present invention relates to a cold storage layer of a low temperature tank to be foamed to form a low temperature tank. Form the inclined surface in front of the main circumferential surface in advance, and form a cold block formed of a cold insulating material such as foam urethane foam, and then bonded, from the upper side of the inclined surface to the round plate and the lining plate of the outer wall of the concrete tank Urethane foam is foamed sequentially and a series of cold layers Insulating layer is formed inside the outer tank made of concrete, and the front surface of the cold block is inclined downward so that the bottom end connecting surface of the cold layer formed of urethane foam in contact with the front slope of the cold block is inclined upwardly. The bottom end connecting surface of the cold storage layer is formed by the front inclined surface of the cold storage layer so that the upper end portion of the bottom end portion of the cold storage layer is gradually inclined to a thin thickness, so that air bubbles are not generated at the bottom tip portion when forming the cold insulation layer. The bottom end of the cold layer reduces the thermal stress caused by the contraction or expansion of the cold block when the low temperature is stored or not stored in the low temperature liquefied gas storage tank. Not only prevents peeling, but also To prevent the wall is one to significantly improve the cold storage function of the low-temperature liquefied gas storage tank as a zoom.
일반적으로 다중각의 저온탱크에 있어서는 탱크의 외체인 콘크리트제외탱크 내주벽면으로부터 내저면까지 우레탄포옴을 취부, 발포시켜서 보냉층을 형성하는 공법이 널리 알려져 있는 것이다.In general, in a multi-angle low temperature tank, a method of forming a cold insulation layer by mounting and foaming a urethane foam from the inner circumferential wall surface of the concrete excluding tank that is the outer body of the tank to the inner bottom is widely known.
따라서 종래에는 상기와 같은 보냉층을 형성함에 있어서 저온액화가스저장탱크를 지지하고 있는 페라이트콘크리트제 기대의 수직저면과 콘크리트제 외탱크 내벽, 또는 내저면 사이가 이루는 우각부의 직각면에 우레탄포옴을 취부, 발포시켜서 보냉층을 형성하여 왔으나, 이는 저온액화가스 저장탱크를 지지하고 있는 페라이트콘크리트제 기대의 주벽면과 콘크리트제 외탱크의 내저면 사이의 우각부인 직각면에 우레탄포옴을 취부발포시켜 주게됨으로서 상기 접촉부 위의 우레탄포옴 보냉층에는 대단히 많은 난조의 기포가 발생하게되어 상기 우각부인 각각의 접합면에 우레탄포옴 보냉층의 성형이 매우 어렵게될 뿐만 아니라, 저온액화가스 저장시 상기의 보냉층이 상온에서 저온분위기로 전환되어 열 수축하게될 때에는 저온액화가스 저장탱크를 지지하고 있는 페라이트콘크리트제 기대와의 접합면상에는 상당한 열응력이 발생하게 되고, 또한 접합면상의 우레탄포옴 보냉층에 발생된 대단히 많은 기포에 의하여 접합면이 쉽게 박리되게 되는 현상이나 균열되는 현상이 나타나게 됨으로서 저온탱크 자체의 안전성이 크게 결여되는 결점이 있었다.Therefore, in forming the above-mentioned cold storage layer, a urethane foam is mounted on a right angled surface formed between the vertical bottom of the ferrite concrete base and the inner wall of the concrete outer tank, or the inner bottom, which supports the low temperature liquefied gas storage tank. , Foaming has been formed to form a cold layer, but this is because by foaming urethane foam on the right angled surface between the main wall surface of the ferrite concrete base supporting the low temperature liquefied gas storage tank and the inner bottom surface of the concrete outer tank In the urethane foam cold insulation layer on the contact portion, a great deal of bubbles are generated, and the urethane foam cold insulation layer is very difficult to form on each joining surface of the right corner portion, and the cold insulation layer is stored at room temperature during low temperature liquefied gas storage. The low temperature liquefied gas storage tank Significant thermal stress is generated on the joint surface with the support made of ferrite concrete, and a phenomenon in which the joint surface is easily peeled off or cracked is caused by a large number of bubbles generated in the urethane foam insulator layer on the joint surface. There was a drawback that the low temperature tank itself is greatly lacking in safety.
본 고안은 이와같은 제반 결점을 해소하기 위한 것으로, 종래와 같이 콘크리트제 외탱크 내주벽면에 우레탄포옴을 취부, 발포시켜서 보냉층을 형성하되, 보냉층의 하부 즉, 저온 액화가스 저장탱크를 지지하고 있는 페라이트콘크리트제 기대의 전주면 외측 전방에 경사면을 형성한 우레탄포옴재의 보냉블록을 배치접착하고, 보냉블록에서부터 콘크리트제 외탱크 내부상면까지 우레탄포옴을 취부 발포시켜 보냉층을 형성하여 보냉층의 저면 선단부와 전방에 경사면을 형성한 보냉블록 사이의 접합면부를 상측으로 갈수록 점차로 얇은 두께로 형성되게하여 보냉층의 저면 선단부에 기포가 발생되는 사례를 제거하고, 보냉층이 저온액화가스등에 의하여 열수축될 때에는 보냉층의 저면 선단부의 상단이 아주 얇은 두께로 형성되어 있었으므로서 이의 열응력을 거의 무시할 수 있게되어 열수축 등에 의한 보냉층의 균열이나 박리현상 등이 발생되지 않게 됨으로서 저온탱크의 보냉성과 안전성을 현저히 향상시킬 수 있도록 한 것으로, 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.다중각 저온탱크(1)의 콘크리트제 외탱크(2) 내주벽전면에 라이닝 플레이트(3)를 부착하고 이의 저면에는 저온재로 된 저온재저판(4)을 상면에 부설한 콘크리트제하면 기대(5)를 분리형성한다. 콘크리트제외탱크(2)의 라이닝플레이트(3)와 콘크리트제 하면 기대(5)의 저온재저판(4) 사이에 라운드플레이트(6)를 취부하고, 콘크리트제하면 기대(5)상에는 저온 액화가스 저장탱크(7) 지지용 페라이트콘크리트제 기대(8)을 환형상으로 설치하고, 이의 상측에 저온 액화가스 저장탱크(7)를 재치시켜 설치한다.The present invention is to solve the above-mentioned shortcomings, the urethane foam is formed on the inner circumferential wall surface of the concrete outer tank and foamed to form a cold layer, but to support the lower portion of the cold layer, that is, the low temperature liquefied gas storage tank The cold block of urethane foam material with the inclined surface formed in front of the outer circumferential surface of the ferrite concrete base in front of the ferrite concrete is placed and bonded, and the urethane foam is mounted and foamed from the cold block to the inner upper surface of the concrete outer tank to form a cold layer. The joint surface between the front end and the cold block having the inclined surface formed at the front becomes thinner gradually to the upper side, thereby eliminating the occurrence of bubbles at the bottom end of the cold layer, and the cold layer is thermally contracted by low temperature liquefied gas. At the time, the upper end of the bottom end of the cold insulation layer was formed with a very thin thickness, The stress can be almost neglected, so that the cold storage layer is not cracked or peeled due to heat shrinkage, and thus the cold storage and safety of the low temperature tank can be remarkably improved, which will be described in detail with reference to the accompanying drawings. A lining plate (3) is attached to the front surface of the inner circumferential wall of the concrete outer tank (2) of the multi-angle low temperature tank (1), and the bottom surface thereof is expected to be made of concrete having a low temperature material plate (4) installed on the upper surface. Separate (5). A round plate 6 is mounted between the lining plate 3 of the concrete removing tank 2 and the low temperature base plate 4 of the lower surface of the concrete base 5, and the low temperature liquefied gas is stored on the base 5 when the concrete is removed. A base 8 made of ferrite concrete for supporting the tank 7 is provided in an annular shape, and a low temperature liquefied gas storage tank 7 is mounted on the upper side thereof.
저온액화가스 저장탱크(7)를 지지하고 있는 보냉질의 페라이트 콘크리트제기대(8) 외측주면에 경사면(9)이 전방에 형성되고 우레탄포옴과 같은 보냉재로 미리 성형된 보냉블록(10)을 배치하여 콘크리트제 하면 기대(5)상의 저온재저판(4)에 접착제(11)를 사용하여 일체로 접착시켜준 다음, 보냉블록(10)의 경사면(9) 상부에서부터 시작하에 콘크리트제 하면 기대(5)의 저온재저판(4), 라운드플레이트(6), 라이닝플레이트(3)의 경로로 우레탄포옴을 취부, 발포시켜 보냉층(12)을 형성한다.An inclined surface 9 is formed on the outer circumferential surface of the insulated ferrite concrete base 8 supporting the low temperature liquefied gas storage tank 7, and an insulated block 10 previously formed of a coolant such as urethane foam is disposed. The low temperature base plate (4) on the lower surface of the concrete (5) is integrally bonded by using an adhesive (11), and then the concrete lower surface (5) starting from the top of the inclined surface (9) of the cold block 10 The urethane foam is mounted and foamed through the path of the low temperature base plate 4, the round plate 6, and the lining plate 3 to form the cold storage layer 12.
보냉층(12)은 페라이트콘크리트제 기대(8)의 외측 주면에 설치된 보냉블록(10)의 전방경사면(9)을 따라 취부발포된 보냉층(12)의 저면선단부(13)는 보냉블록(10)의 전방 경사면(9)에 의하여 상단이 점차로 얇아지는 경사상의 형태로 형성한다.The cold insulation layer 12 is a bottom end portion 13 of the cold insulation layer 12, which is mounted along the front inclined surface 9 of the cold insulation block 10 provided on the outer main surface of the base 8 made of ferrite concrete, the cold insulation block 10 It is formed in the form of an inclined shape of the top is gradually thinned by the front inclined surface (9).
이와같이 구성된 본 고안은 미리 성형되어 저온 액화가스 저장탱크(7)를 지지하고 있는 페라이트콘크리트제기대(8) 외측주면에 배설된 보냉블록(10)의 전방경사면(9)의 상부에서부터 콘크리트제외탱크(2)의 내주벽에 부착된 라이닝 플레이트(3)의 상부까지 우레탄포옴을 발포하여 보냉층(12)을 형성하게 되는데, 이때 보냉블록(10)의 전방 경사면(9)에 의하여 취부, 발포되어 형성되는 우레탄포옴의 보냉층(12)의 저면선단부(13)는 점차로 상단이 얇아지는 상향 경사상의 형태로 형성됨으로서 보냉층(12)의 저면 선단부(13)에는 난기포현상이 전혀 발생되지 않게되어 보냉층(12)의 열응력을 균일하게 유지할 수 있을뿐만 아니라 보냉층(12)의 저면 선단부(13)는 상단이 가느다란 경사상으로 형성되게 됨으로서 저온 액화가스 저장탱크(7)에 저온의 액화가스저장시 상온때와의 온도 차이에 의하여 보냉블록(10)이 열수축하게될 때 보냉층(12)의 저면 선단부(13)에는 열응력이 발생하게 되나 보냉층(12)의 저면선단부(13) 부군에 발생되는 열응력의 분포는 보냉층(12)의 저면선단부(13) 상단에 발생되는 열응력에 비하여 하측으로 내려갈수록 점차로 두터워지는 부분이 상당히 커지게됨으로서 보냉층(12)의 저면선단부(13)의 상단측에 발생하는 열응력은 극히 작아지는 상태가 되어 저면 선단부(13)의 상단측은 보냉블록(10)의 열수축시 전방의 경사면(9)에 접합된 상태로 접동하게 되므로서(제2도의 가상선부분 참조) 열응력으로 인한 보냉층(12)의 저면선단부(13)는 보냉블록(10)의 경사면(9)에서 박리되거나 균열되는 등의 현상이 완벽하게 방지되는 것이다.The present invention constructed as described above has a pre-formed concrete tank (from the upper portion of the front inclined surface 9 of the cold block 10 disposed on the outer circumferential surface of the ferrite concrete raising base 8 which is preformed and supporting the low temperature liquefied gas storage tank 7). The urethane foam is foamed up to the upper portion of the lining plate 3 attached to the inner circumferential wall of 2) to form the cold storage layer 12, wherein the cold inclined surface is mounted and foamed by the front inclined surface 9 of the cold block 10. The bottom end portion 13 of the cold insulation layer 12 of the urethane foam is formed in an upwardly inclined shape in which the top is gradually thinned, so that no air bubbles are generated in the bottom end portion 13 of the cold insulation layer 12 at all. Not only can the thermal stress of the layer 12 be maintained uniformly, but the bottom end portion 13 of the cold storage layer 12 is formed at a slanted slope at the top thereof, so that the low temperature liquefied gas is stored in the low temperature liquefied gas storage tank 7. When saving When the cold block 10 is thermally contracted due to a temperature difference from the on-time, thermal stress is generated in the bottom end portion 13 of the cold storage layer 12, but is generated in the bottom end portion 13 subgroup of the cold storage layer 12. The thermal stress distribution is considerably larger as the portion becomes thicker toward the lower side than the thermal stress generated at the top of the bottom tip 13 of the cold storage layer 12, so that the top of the bottom tip 13 of the cold storage layer 12 becomes larger. The thermal stress generated on the side becomes extremely small, and the upper end side of the bottom end portion 13 slides in a state of being joined to the inclined surface 9 at the front during thermal contraction of the cold block 10 (imaginary line of FIG. 2). The bottom end portion 13 of the cold storage layer 12 due to thermal stress is to prevent the phenomenon such as peeling or cracking on the inclined surface 9 of the cold block 10.
이와같은 본 고안은 우레탄포옴을 취부 발포시켜서 보냉층을 형성함에 있어서 보냉블록의 전방 경사면으로부터 취부, 발포시켜 보냉층을 형성하여, 보냉층의 저면 선단부의 상단을 아주 얇은 두께로 형성하고 점차로 하향할수록 두껍게 형성되므로서 보냉층의 저면선단부에 난기포가 발생되는 사례없이 간단히 보냉층을 형성시킬 수 있는 시공작업상의 이점이 있을뿐만 아니라, 보냉층의 저면 선단부의 상단이 점차로 얇아지는 경사상의 형태로 형성하게 되므로서 저온 액화가스를 저장할시 저온 분위기에서의 열수축에 따르는 열응력을 극히 적어지게 되고 이에 따라 보냉층의 저면선단부의 박리현상이나 균열현상을 완벽하게 방지할 수 있어 저온탱크의 보냉성이나 안전성을 현저하게 향상시킬 수 있는 특징을 지닌 유용한 고안인 것이다.In this invention, the urethane foam is mounted and foamed to form a cold layer, and the cold layer is formed from the front inclined surface of the cold block and foamed to form a cold layer. The upper end of the bottom of the cold layer is formed in a very thin thickness and gradually downwards. As it is thickly formed, there is an advantage in the construction work that can easily form a cold storage layer without the occurrence of turbulence at the bottom end of the cold storage layer, and is formed in an inclined shape in which the top of the bottom end of the cold storage layer becomes thinner gradually. Therefore, when storing low temperature liquefied gas, the thermal stress due to heat shrinkage in the low temperature atmosphere is extremely reduced, and thus, it is possible to completely prevent the peeling or cracking of the bottom end of the cold layer, and thus the cold storage temperature and safety of the low temperature tank. It is a useful design with features that can significantly improve the.
